APP/APG create a custom EXIF tag for the stitched pano that describes the pano FOV.

Autopano Tour reads this to set the values for pano FOV automatically.

If you post-process the stitched pano before adding it to APT then your image editor will probably remove that custom EXIF tag and APT will apply a default Pano FOV of 360x180.

You need to change those default values to match the values originally recorded in the custom EXIF tag in the stitched pano.

Three options:

1. Use an EXIF viewer to read that custom tag pano make a manual record the pano FOV data for later manual entry to APT, before manipulation the image in your image editor.

2. Add the un-processed stitched pano to APT and make a manual record of the pano FOV detected from the custom EXIF tag - then post-process your pano image and when next adding it to APT then enter those pano FOV values you recorded before yur image processing.

3. When stitching your pano always set the projection range to 360x180. Only problem with this is that, unlike Pano2VR, Autopano Tour does not yet (despite repeated requests!) offer a simple way to restrict the viewing FOV range.
